JOHN F. BYRNE, OF BATTLE GREEK, MICHIGAN, ASSIGNOB TO KELLOGG TOASTEDCORN FLARE COMPANY,' OF BATTLE CREEK, MICHIGAN.

BOX on CARTON.

To all whom it may concern:

Be it known that I, JOHN F. BYRNE, a citizen of the United States,residin a't Battle Creek, Michigan, have invente .certain new and usefulImprovements in Boxes or Cartons, of which the following is aspecification This invention relates to improvements in boxes orcartons.

The main object of this invention is to providea carton or package ofordinary construction with special devices and means, including innerflaps with cut away portions whereby a flap of the ackage may be readilyopenedand a part of the contents removed and the package againtemporarily closed to effectively protect and preserve the contentsduring a brief period, as, for instance,

the few days that will ordinarily elapse after a package of preparedfood has been opened.

Further ob ects, and objects pertaining to details and economies ofconstruction and use will fully appear from the detailed de- I scriptionto follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

. Structures constituting preferred embodi- 'ments of my invention areclearly illustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a perspective view of a sealed box or carton embodying thefeatures of my invention. Fig. II is a perspective view thereof afterthe same has been opened, with the mouth of the inner casing or bagprotruding. Fig. III is a detail view similar to Fig. II, wit-h theinner casing or sack omitted. Fig. IV is a detail perspective view ofthe upper part of the carton or package before closing and sealing theflaps. Fig. V is a detail transverse section taken on a linecorresponding to line 55 of Fig. I, with the discharge lid closed, theopen posi tion being shown by dotted lines. 'Fig. VI is a plan view ofthe blank used in forming the box.

In the drawing, similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, my improved Specification a team 1mm. p t t19, 1912, Application filed November 8, 1911. Serial 'No'. 858,889.

and top or end flaps 9, 10, 11 and 12, re-

spectively. When the blank is set up, the s de portlons 1 and 3 opposethe side portlons 2 and 4, res ectively. The side portion 1'1s providedwit a flap 13 which is folded within and secured to the side wall 4. Theend flaps are folded upon each other and glued in the well-known manner,the blank eing scored alon the folding lines, as indicated by dottedines. In folding the top flaps, the flaps 10 and 12 are first folded andconstitute the inner flaps, flap 9 the intermediate fiap, and flap 11the outer flap. Flap 11 is provided with a tongue 14 at its outer edgewhich is centrally disposed. Oblique scoring lines 1515 extend from thebase of the tongue 14 across the flap 11 to the opposite side of thecarton. A slit 17 is made 1n the fla 9 just beneath the base of thetongue 14 t hr tucking the tongue after the box has been opened. Scoringlines 16- 16, correspondin to the lines 1515, are in the flap 9, extening from the opposite ends of the slit 17. The end flaps l0 and 12 arecut away on lines 1818 corresponding to the scorings 15 and 16,.andproject at 19 to reinforce the outer flaps near the line of severance ofthose parts, thereb facilitating the opening of the package. Swing tothe fact that these severing scorings are oblique, the operation of thecarton sealing machine is not interfered with, because there is notendency of the machine to fold along these lines when the machine is inoperation when sealing the carton. The tongue 14 is left free, glue notbeing distributed upon the same.

Within the carton is an open mouthed pa per sack or other container forthe contents, which can be readil opened out when the flaps are severedan the lid openedv out, as seen in Fig. II. This makes a versatisfactory spout for pouring out a portion of the contents. Afteropening, the sack can be folded back inside the carton and the tongue 14tucked under the slit 17, as shown, thus making a temporary closure ofthe package. which is big ly satisfactory and of advantage where thepackage contains breakfast food, for instance.

From this description, it will be seen that the general characteristicsof the carton are not modified.

I believe that my invention is adapted to any form of carton havingfolding flaps for sealing the same.

The carton here illustrated is identical with the carton in common use,with my feature added, and is very readily sealed by machinery; forinstance, such as is shown in Patent No. 976,346, of Nov. 22nd, 1910, toJohnson, for carton sealing machine.

When the parts are folded together, the different scoring linessubstantially coincide at the heavy shoulder formed by the edges of thecut away inner flaps, but owing to the expansion of paper and thevariations in the movement of the sealing machinery, the parts do notabsolutely coincide, and by this means, the different scoring linesslightly overlap, making a perfect sealing of the package, yet one whichcan be very readily broken open along the scorings indicated because ofthe shoulder, as aforesaid.

When a knife is used to open the package, scoring may be dispensed with,and the lid with the tucking tongue will be veryefiicientz The scoring,however, is of advantage in securing the desired results and a veryconvenient package.

. I desire to claim the structure specifically broadly as pointed out inthe appended c alms.

Having thus described my invention, what I claim as new and desire tosecureby Letcorresponding to the base of'the tongue andclosed thereby,andsevering scoringlines in the outer overlying flaps extending from thebase of said tongue and the ends of said slit obliquely andtransverselyto the fold of said flap at the opposite side of the saidcarton to facilitate opening the same, the

shortened inner flaps being cut vaway along the line of said severingscoring, and an inner container with an open mouth for extension throughthe opening thus formed so that the package can be opened and closed andthe tongue inserted in the slit for retaining the same in the closedosition after the sealing is broken, as speci ed.

2. A carton or box, the end of which is closed by shortened inner flapsand overlapping outer flaps sealed together by a suitable adhesive, theoutermost fla of which has a tongue projecting beyon its outer edge, aslit in the underlying flap in position corresponding to the base of thetongue and closed thereby, and severing scoring lines in the outeroverlying flaps extending from the base of said tongue and the ends ofsaid slit obliquely and transversely to the fold of said flap at theopposite side of the said carton to facilitate opening the same, theshortened inner flaps being cut away along the line of said severingscoring, so that the package can be opened and closed and the tongueinserted in the slit for retaining the same in the closed position afterthe sealing is broken, as specified.

3. A carton or box, the end of which is closed by overlapping flapssealed together, the outermost of which is provided with a tongue andthe said overlapping flaps being scored by lines of severing scoringstransverse to the line offolding of said flaps, the

inner flaps being partially cut away to weaken the lid on said scoringlines for opening, as specified.

4. A carton or ,box, the end ofwhichis closedby overlapping flaps sealedto ether by a suitable adhesive, the outermost ap of which is providedwith a tongue projecting beyond its edge, and a slit in the underlyingflap corresponding to the base of the tongue,-

so that the package can be opened and closed and the tongue inserted inthe slit for retaining'the same in closed position after the sealing isbroken, as 'speclfied. v

, 5; A carton or box, the end of which is closed by overlapping flapssealed together, the outermost of which is provided with a tongue, andthe said overlapping flapshaving lines of severing scoringsextendingfrom the base of said tongue obliquely transverse to the lineof folding of said flaps, as specified.

6. A carton or box, the end of which is closed by overlappingflapssealed together, the outermost of which is provided with a tongue,and the said overlapping flaps having lines of severing scormgsextending from the base of said tongue transverse to the line of foldingof said flaps, as specified.

In-witness whereof, I have hereunto set my hand and seal in the presenceof two wltnesses.
